Defcon Blade Works Proelia Features a 4.00" black finish D2 steel tanto blade and a 5.00" tan G-10 handle. Overall length is 9.00". Comes complete with a spare pocket clip, a vertical/horizontal carry nylon sheath and an adjustment tool. This knife uses a ball bearing system for opening. This is a feature that separates the Proelia from most of the knives on the market today. The bearing system allows this 100% manual flipper to open and close easily and smoothly.
